In an experiment to measure the lifetimes of parts manufactured from a certain aluminum alloy, 73 parts were loaded cyclically until failure. The mean number of kilocycles to failure was 783, and the standard deviation was 120. Let ? represent the mean number of kilocycles to failure for parts of thi

A certain microwave oven delivers 750. watts (J/s) of power to a coffee cup containing 50.0 g water at 25.08C. If the wavelength of microwaves in the oven is 9.75 cm, how long does it take, how many photons must be absorbed, to make the water boil? The specific heat capacity of water is 4.18 J/8C ? g

Cell Phone Lifetimes A recent study of the lifetimes of cell phones found the average is 24.3 months. The standard deviation is 2.6 months. If a company provides its 33 employees with a cell phone, find the probability that the mean lifetime of these phones will be less than 23.8 months. Assume cell
